NTL's technical support is non-existent.
We cancelled the TV and phone package 6 months ago yet they still tried to take the money from the account. We barred NTL from taking money from the account, they sent a nasty letter saying they'd take us to court for using services and not paying for them!
They don't know their arse from their elbow.
(Apology's to all those offended, but its true!)
From personal experience, 56k NTL is shocking. Always busy. A complete waste of money. Of course, due to the above warblings I'm probably biased.
Go BT Broadband. Its currently cheap. Its veh veh fast. And primarilly, you pay for a service you can use.
Go on treat yourself. ;-)
